The molecules of a liquid substance are closely packed together to each other. So as a result, liquids are denser than gases.
<h3>
What is the difference between the density of liquid and gas?</h3>
A mass of gas will have a much larger volume compared to the same mass of liquid. This is because it has a much lower density. The density of gaseous oxygen is 0.0014 g/cm3. Density is ρ=Mass Volume. We know that gas will uniformly occupy more space than liquid whatever volume is available to it. On the other hand, solids and liquids, are closely packed as compared to gas and are high-density materials where ρ is relatively constant.
So we can conclude that the molecules of a liquid substance are closely packed together with each other. So as a result, liquids are denser than gases.

Answer:
12.5 g of Li are needed in order toproduce 0.60 moles of Li₃N
Explanation:
The reaction is:
6Li(s) + N₂(g) → 2Li₃N(s)
If nitrogen is in excess, the lithium is the limiting reactant.
Ratio is 2:6
2 moles of nitride were produced by 6 moles of Li
Then, 0.6 moles of nitride were produced by (0.6 .6)/ 2 = 1.8 moles of Li
Let's convert the moles to mass → 1.8 mol . 6.94 g/ 1mol = 12.5 g of Li
A thermocouple is a sensor used to measure temperature. Thermocouples are made with two wires of different metals, joined together at one end to form a junction. ... Naturally, a thermocouple outputs a millivolt signal, therefore, as the resistance changes, the change in voltage can be measured.

Umm...Well...
Heisenberg's Uncertainty Principle says that we can never know both the position and rate of change of a particle at any time. We can only know one or the other. This leads to rather silly jokes that deal with uncertainty, probability, and superposition. So, saying that "Heisenberg may have slept here" is essentially saying that it is uncertain if Heisenberg slept there or not, making for a rather silly, but slightly unfunny physics joke.
